Application filed April 20, 1908. Serial No. &28,111.

To all whom it may concern:

Be it knownthat LJosnri-r RoBEnTMATn- EWB, a citizen of the United States, and a resident of Fairbanks, District of Alaska, have invented a new and improved Hose Connection for Steam Thaw-Points, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide novel'details of construction for hose connections, which enables the attachment in a simple and secure manner, of one end of a steam conducting hose upon the body of a thaw point, and which will not be affected by the jar incidental to driving the thaw point into frozen ground, that is to be thawed by steam passing down through saidthaw oint.

The invention consists in the nove construction and combination of parts as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specifi cation, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partly sectional and broken side view of a thaw point, and of a hose section secured by one end upon the head portion of the thaw point by means of the improved connection; Fig. 2 is a broken side elevation of the thaw'point; and Fig. 3 is a partial plan view.

In the drawings, 5 indicates the body of a thaw oint, preferably formed of steel, said body being cylindrical "and having an axial bore a, of suitable diameter. The normally lower end of the body 5-terminates in a point 5, and near said point the lower end of the bore a is intersected by'a transverse hole a, that passes through the body of the thaw point,- A sufficient length is given to the ody 5 for its effective service, and at a mint near the poll orhead 5 a d'iametrica enlargement and lateral branch 5 of the body 5 is produced, to aiford material wherein to form the improved hose connection.

As ap ears in Fig. 1, the axial bore a is extended aterally at its upper end, thus producing an inlet perforation a equal in diametc? to that of the bore a. Concentric with the perforation a, an annular bore 6 isformed in the enlargement and branch 5 for a suitable depth, leaving a conicalnipple c in tact with the body of the thaw point.

The diameter of the counterbore bis such,- thatan annular recess c is formed around the nipple of a size that permits the neat insertion of an end of a heavy pliable steam hose 6 therein, so that the true end of said hose will bear upon the bottom wall of the recess.

The preferred means for removably securing the end portion of the hose 6 in connection with the counterbored portion of the thaw point head, consists of the following details. U don the hose 6, near its end, two clamping pl ates 7 are tightly clamped by the bolt and nuts (1, said plates-having notches (l in'thcir edges. A yoke, formed with a curved head or crown 8 and two parallel limbs 8, is provided with hooks or other with the notches d of the clamping plates 7 body of the thaw point 0 posite the branch 5. In the crown 8 of t 1e yoke, a tapped perforation is formed, that receives the threaded bod r of an eye bolt 9, which by adjustment, will bear upon the body 5 and draw the hose forcibly against the bottom of the counterbore b.

for connecting a steam hose with the head portion of a thaw point, affords a very strong and durable connection therefor, which will resist shock to which a hose couppoint is repeatedly struck with a sledge, for driving the point down into the frozen soil.

In case the hose 6 becomes Worn out from use, or injured where it is joined to the thaw point, by continued bendin at that point, it may be repaired quickly y first cutting it off at a solid art of the hose and then .re

connecting the ose by means of the clamp.

as hereinbefore described.

Having thus described my. invention, I claim as new and desire to secure a Letters Patent:

1. The combination with a thaw point body having an annular recess in one side thereof and a conical nipple disposed centrally in said recess, the thaw oint body having a longitudinal bore and a ateral bore extending throu h the nipple and communicating with the ongitudmal bore, of a hose section adapted to be inserted in the said recess and over the nipple, a clampin device clamped upon the hose section, an having projecting ends rovided with notches, a yoke having lim s embracingthe body of means for engaging the ends of the limbswhen the yoke is caused to embrace the ling is subjected when the head of the thaw It will be seen that the described means the-thaw point, the said limbs being provided at their ends with hooks for engaging i said recess.

I said notches, and adjustable meens engsging the yoke and bearing on the thew point body to draw the hose against the bottom of 2. The combination with it longitudinally perforated therein extending laterally near the upper end of the body, said body having :1 counterbored recess therein concentric with the lateral extension of the perforation, and a conical :oi ple formed on the bottom of the recess an around the perforation therein, of a steem hose section havin an end thereof seated in the recess over t e ni. ple, and a; clamping device for holding the drawn into the recess,. com rising two clam iing plates secured upon t e hose near the t Lew thaw point body, the perforation siege;

point body, the said plates having notches in their edges, e yoke having parallel limbs extended from en integral crown member, said limbs embracing toe body of the thaw ior engagement with the notches of the clamping plates, and a. screw bolt tapping the, crown of the yoke and pressing at its end on the thaw oint body at s point oppm site the said nipp e.
